REDUCED EXPOSURE: WHAT DOES IT TELL US AND WHAT DOESN’T IT TELL US?

When someone is exposed to lower levels of harmful substances we know their exposure has decreased. However,this alone does not tell us how much their health risk has decreased.

[THR Explained @THRExplained]

WHAT DOES “REDUCED RISK” MEAN IN TOBACCO HARM REDUCTION?
It simply means less risk compared with something riskier. For someone who smokes, it means choosing an option that may carry less risk than smoking.

In October 2025, our event explored how Nigeria could adapt Sweden’s approach through evidence-based policies and accessible, acceptable and affordable lower-risk alternatives.

So the conversation shouldn’t just be about whether someone quits or continues. We should also ask where the harm comes from and whether there are ways to reduce exposure to it.

[THR Explained @THRExplained]

Quitting should always be encouraged but what about those who continue to smoke despite trying to quit? Reducing the harm from continued smoking deserves a place in the conversation. It’s not about making smoking safe it's about reducing risk.

“Safe” or “dangerous” isn’t always the whole story. In tobacco harm reduction the better question is how does the risk compare with continuing to smoke?
Risk is relative.

ARE ALL NICOTINE OR TOBACCO PRODUCTS EQUALLY HARMFUL?

[THR Explained @THRExplained]

5. “IF THEY’RE NOT RISK-FREE, WHY CONSIDER THEM?”
They don’t have to be risk-free to be a lower-risk option. For adults who smoke, switching away from cigarettes may reduce exposure to harmful substances from burning tobacco. That’s harm reduction.

5 Things people often get wrong about Nicotine pouches. There’s a lot of confusion around nicotine pouches.
Let’s clear up 5 common misconceptions 👇

[THR Explained @THRExplained]

4. “NICOTINE IS WHAT MAKES CIGARETTES SO HARMFUL.”
Nicotine keeps people dependent on cigarettes but the smoke from burning tobacco contains many toxic substances that cause much of the serious harm linked to smoking.

[THR Explained @THRExplained]

3. “NO SMOKE MEANS NO RISK.”

Not exactly. Nicotine is addictive and nicotine pouches still carry risks. The fact that there’s no tobacco burning doesn’t make them harmless.

[THR Explained @THRExplained]

2. “THEY’RE THE SAME AS SNUS.”
Not really. Snus contains tobacco while nicotine pouches don’t. They may look similar but they’re different products.

[THR Explained @THRExplained]

1 . “NICOTINE POUCHES CONTAIN TOBACCO.”
Nope. They don’t contain tobacco leaf. They contain nicotine and other ingredients.

[CAPHRA (Coalition of AP Harm Reduction Advocates) @caphraorg]

New Zealand's tobacco sales fell more than 20 percent in 2025 alone, and have more than halved over the past decade. This is real world evidence policymakers across Asia Pacific should study. #AFN26, #NZ, #AsiaPacific https://t.co/CovqayHv8f https://t.co/KZ5gr32u22

[Bludn Gore (Supervisor) @Bludn_Gore]

Australia is debating whether cigarettes should be cheaper or criminals should be chased harder. That misses the third and most important lever: make regulated, substantially safer alternatives genuinely accessible to adults who smoke. A credible tobacco policy must reduce smoking, reduce crime and give consumers a lawful way out.

[Arielle Selya @ArielleSelya]

"Nicotine isn’t harmless—but treating every nicotine product as equally dangerous obscures an important public-health distinction.

From cigarettes and vaping to pouches, gum, and patches, cardiovascular risk falls along a continuum shaped not just by nicotine, but by how it is delivered, especially by whether tobacco is burned."

[THR Explained @THRExplained]

The next time someone says “I miss smoking,” ask what they actually miss . Is it the nicotine,the habit or both? That difference matters when we talk about quitting and tobacco harm reduction.

[THR Explained @THRExplained]

IS IT NICOTINE YOU MISS, OR THE HABIT OF VAPING OR SMOKING?

When people quit smoking or vaping they don’t only have to deal with nicotine cravings. Sometimes they also miss the routine and behaviour that became part of their day.

[THR Explained @THRExplained]

This is why quitting can be difficult even when someone really wants to stop. They are not only breaking their dependence on nicotine,they are also trying to break routines they may have repeated hundreds of times.

[THR Explained @THRExplained]

This is where behavioural substitutes can help some people.Chewing gum,having a mint,drinking water or keeping your hands and mouth busy can help replace parts of that familiar routine even though they don’t replace nicotine.
